Hello Laura,
I am Kara Maynard Sper. My grandfather was Absalom Maynard Jr. That picture hung in my Aunt Jackie's house and I remember if fondly as a child. My grandfather also gave a print of this to my Aunt Yvonne. On the back of the print, it's stated on the back of it that my grandfather's mother is the one in the middle. Delia.
This is a great testimony that you have put together to honor your grandfather.
Sincerely,
Kara Maynard Sper
